AprsPlotter decodes and plots position reports found in APRS messages
AprsPlotter provides an OLE/COM (Automation) output that gives the current position of each station whose data has been received. CombiPlotter from COAA uses the OLE/COM output and allows you to display the APRS data together with aircraft decoded by PlanePlotter, ships decoded by ShipPlotter as well as satellites and radio sondes, all on the same chart.
